International B110 vehicles utilized 194 bulb size for front side marker applications and 97 bulb size for rear side marker positions. The replacement chart documents bulb specifications across 1959 to 1960 production years.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The International B110 uses two distinct bulb types across its front and rear side marker positions for the 1959-1960 model years, with each position requiring a specific and non-interchangeable type.
The 194 bulb serves as the front side marker across both model years covered in the specifications. It follows the ANSI standard recognized in the US and Canada.
The 194 is a T10 miniature wedge bulb, meaning it uses a wedge-style base rather than a pin or bayonet fitting. It operates at 12 volts and draws 3.78 watts, placing it among the lower-wattage bulbs in automotive applications.
The rear side marker position on the International B110 uses the 97 bulb for the 1959-1960 model years, also conforming to the ANSI standard for the US and Canadian markets.
The 97 bulb uses a BA15s bayonet base, which is a single-contact bayonet mount. It operates at 12 volts and draws 13 watts, a notably higher wattage than the 194 used at the front.
The 97 bulb is described as a variant of the 1156. While the two share a BA15s base type, they are not identical, and this distinction carries relevance for fitment purposes when sourcing replacements.
The front and rear side marker bulbs on the International B110 are not interchangeable. The 194 uses a wedge base while the 97 uses a bayonet base, making the two physically incompatible with each other's sockets.
Both the 194 and 97 are single-filament bulbs, meaning each serves a single lighting function rather than combining multiple functions such as running and braking into one unit.
